The RX series tripods are the largest of the SIRUI tripods. With their high load of up to 25kg, they are particularly suited to working in the studio and with large, heavy DSLR and video cameras. The special feature of the RX series is its removable mounting plate. It can be replaced with the 75mm half ball adapter (and can be used with the optional SIRUI Y-75B levelling half ball). This means that it can be used on a SIRUI video tilt head, for example. To make changing between the plate and the half ball easier, an Allen key is integrated into the stabilising hook.

The leg tubes are made from 10-layer carbon fibre, making the tripod extremely lightweight but very stable. Depending on the surface, the non-slip rubber feet can be replaced with robust stainless steel spikes (included).
